These data Every dsPIC33FJXXXMCX06A/X08A/X10A device spaces can beconsidered either separate (for some contains 2 Kbytes of dual ported DMA RAM located at DSP instructions) or as one unified, linear address the end of Y data space. Memory location is part of Y range (for MCU instructions). The data spaces are data RAM and is in the DMA RAM space, and is accessed using two Address Generation Units (AGUs) accessible simultaneously by the CPU and the DMA and separate data paths. This feature allows certain controller module. DMA RAM is utilized by the DMA instructions to concurrently fetch two words from RAM, controller to store data to be transferred to various thereby enabling efficient execution of DSP algorithms, peripherals using DMA, as well as data transferred from such as Finite Impulse Response (FIR) filtering and various peripherals using DMA. The DMA RAM can be Fast Fourier Transform (FFT). accessed by the DMA controller without having to steal cycles from the CPU. The X data space is used by all instructions and supports all addressing modes. There are separate When the CPU and the DMA controller attempt to read and write data buses for X data space. The X read concurrently write to the same DMA RAM location, the data bus is the read data path for all instructions that hardware ensures that the CPU is given precedence in view data space as combined X and Y address space. accessing the DMA RAM location. Therefore, the DMA It is also the X data prefetch path for the dual operand RAM provides a reliable means of transferring DMA DSP instructions (MAC class). data without ever having to stall the CPU. The Y data space is used in concert with the X data space by the MAC class of instructions (CLR, ED, EDAC, MAC, MOVSAC, MPY, MPY.N and MSC) to provide two concurrent data read paths. Both the X and Y data spaces support Modulo Addressing mode for all instructions, subject to addressing mode restrictions. Bit-Reversed Addressing mode is only supported for writes to X data space. All data memory writes, including in DSP instructions, view data space as combined X and Y address space. The boundary between the X and Y data spaces is device-dependent and is not user-programmable. All Effective Addresses are 16 bits wide and point to bytes within the data space. Therefore, the data space address range is 64 Kbytes, or 32K words, though the implemented memory locations vary by device.  2009-2012 Microchip Technology Inc. DS70594D-page 41

The FSCM delay is possible after SYSRST is released: time is nominally 500 s and provides additional time for the oscillator and/or PLL to stabilize.

The Interrupt Vector Table (IVT) is shown in Figure7-1. The IVT resides in program memory, starting at location 000004h. The IVT contains 126 vectors consisting of eightnonmaskable trap vectors plus up to 118 sources of interrupt. In general, each interrupt source has its own vector. Each interrupt vector contains a 24-bit wide address. The value programmed into each interrupt vector location is the starting address of the associated Interrupt Service Routine (ISR). Interrupt vectors are prioritized in terms of their natural priority; this priority is linked to their position in the vector table. All other things being equal, lower addresses have a higher natural priority. For example, the interrupt associated with vector 0 will take priority over interrupts at any other vector address.  2009-2012 Microchip Technology Inc. DS70594D-page 85

dsPIC33FJXXXMCX06A/X08A/X10A 7.3 Interrupt Control and Status The IPC registers are used to set the interrupt priority Registers level for each source of interrupt. Each user interrupt source can be assigned to one of eight priority levels. dsPIC33FJXXXMCX06A/X08A/X10A devices implement The INTTREG register contains the associated a total of 30 registers for the interrupt controller: interrupt vector number and the new CPU interrupt • INTCON1 priority level, which are latched into vector number • INTCON2 (VECNUM<6:0>) and Interrupt level bit (ILR<3:0>) • IFS0 through IFS4 fields in the INTTREG register. The new interrupt priority level is the priority of the pending interrupt. • IEC0 through IEC4 • IPC0 through IPC17 The interrupt sources are assigned to the IFSx, IECx and IPCx registers in the same sequence that they are • INTTREG listed in Table7-1. For example, the INT0 (External Global interrupt control functions are controlled from Interrupt 0) is shown as having vector number 8 and a INTCON1 and INTCON2. INTCON1 contains the natural order priority of 0. Thus, the INT0IF bit is found Interrupt Nesting Disable bit (NSTDIS) as well as the in IFS0<0>, the INT0IE bit in IEC0<0> and the INT0IP control and status flags for the processor trap sources. bits in the first position of IPC0 (IPC0<2:0>). The INTCON2 register controls the external interrupt Although they are not specifically part of the interrupt request signal behavior and the use of the Alternate control hardware, two of the CPU Control registers Interrupt Vector Table. contain bits that control interrupt functionality. The CPU The IFS registers maintain all of the interrupt request STATUS register, SR, contains the IPL<2:0> bits flags. Each source of interrupt has a status bit, which is (SR<7:5>). These bits indicate the current CPU set by the respective peripherals or external signal and interrupt priority level. The user can change the current is cleared via software.

These control bits are used to individually enable together with IPL<2:0>, also indicates the current CPU interrupts from the peripherals or external signals. priority level. IPL3 is a read-only bit so that trap events cannot be masked by the user software.

In general, the user must clear the interrupt flag in the appropriate IFSx register for the source of interrupt that the ISR handles. Otherwise, the ISR will be re-entered immediately after exiting the routine. If the ISR is coded in assembly language, it must be terminated using a RETFIE instruction to unstack the saved PC value, SRL value and old CPU priority level.  2009-2012 Microchip Technology Inc.

FRMEN (SPIxCON2<15>) = 1 and SSEN (SPIxCON1<7>) = 1 are exclusive and invalid. In Frame mode, SCKx is continuous and the Frame sync pulse is active on the SSx pin, which indicates the start of a data frame. Note: Not all third-party devices support Frame mode timing. Refer to the SPI electrical characteristics for details. 4. In Master mode only, set the SMP bit (SPIxCON1<9>) to a ‘1’ for the fastest SPI data rate possible. The SMP bit can only be set at the same time or after the MSTEN bit (SPIxCON1<5>) is set. 5. To avoid invalid slave read data to the master, the user’s master software must guarantee enough time for slave software to fill its write buf- fer before the user application initiates a master write/read cycle. It is always advisable to pre- load the SPIxBUF transmit register in advance of the next master transaction cycle. SPIxBUF is transferred to the SPI shift register and is empty once the data transmission begins. DS70594D-page 198  2009-2012 Microchip Technology Inc.

On devices without a DMA module, the ADC has • Section 16. “Analog-to-Digital Converter 16 result buffers. ADC conversion results are (ADC)” (DS70183) stored sequentially in ADC1BUF0-ADC1BUFF • Code Samples regardless of which analog inputs are being • Application Notes used subject to the SMPI<3:0> bits (AD1CON2<5:2>) and the condition described • Software Libraries in 1c above. There is no relationship between • Webinars the ANx input being measured and which ADC • All related dsPIC33F/PIC24H Family Reference buffer (ADC1BUF0-ADC1BUFF) that the Manuals Sections conversion results will be placed in. • Development Tools 3. On devices with a DMA module, the ADC mod- ule has only 1 ADC result buffer, (i.e., ADC1BUF0), per ADC peripheral and the ADC conversion result must be read either by the CPU or DMA controller before the next ADC conversion is complete to avoid overwriting the previous value. 4. The DONE bit (AD1CON1<0>) is only cleared at the start of each conversion and is set at the completion of the conversion, but remains set indefinitely even through the next sample phase until the next conversion begins. If application code is monitoring the DONE bit in any kind of software loop, the user must consider this behavior because the CPU code execution is faster than the ADC. As a result, in manual sam- ple mode, particularly where the users code is setting the SAMP bit (AD1CON1<1>), the DONE bit should also be cleared by the user application just before setting the SAMP bit. 5. On devices with two ADC modules, the ADCxPCFG registers for both ADC modules must be set to a logic ‘1’ to configure a target I/O pin as a digital I/O pin. Failure to do so means that any alternate digital input function will always see only a logic ‘0’ as the digital input buffer is held in Disable mode.

All specified values are based on characterization data for that particular oscillator type under standard operating conditions with the device executing code. Exceeding these specified limits may result in an unstable oscillator operation and/or higher than expected current consumption. All devices are tested to operate at “min.” values with an external clock applied to the OSC1/CLKI pin. When an external clock input is used, the “max.” cycle time limit is “DC” (no clock) for all devices. 3: Measurements are taken in EC mode. The CLKO signal is measured on the OSC2 pin. 4: Data for this parameter is preliminary. This parameter is characterized, but not tested in manufacturing.  2009-2012 Microchip Technology Inc.

dsPIC33FJXXXMCX06A/X08A/X10A 27.0 HIGH TEMPERATURE ELECTRICAL CHARACTERISTICS This section provides an overview of dsPIC33FJXXXMCX06A/X08A/X10A electrical characteristics for devices operating in an ambient temperature range of -40°C to +150°C. The specifications between -40°C to +150°C are identical to those shown in Section26.0 “Electrical Characteristics” for operation between -40°C to +125°C, with the exception of the parameters listed in this section. Parameters in this section begin with an H, which denotes High temperature. For example, parameter DC10 in Section26.0 “Electrical Characteristics” is the Industrial and Extended temperature equivalent of HDC10. Absolute maximum ratings for the dsPIC33FJXXXMCX06A/X08A/X10A high temperature devices are listed below. Exposure to these maximum rating conditions for extended periods can affect device reliability. Functional operation of the device at these or any other conditions above the parameters indicated in the operation listings of this specification is not implied. Absolute Maximum Ratings(1) Ambient temperature under bias(4).........................................................................................................-40°C to +150°C Storage temperature.............................................................................................................................. -65°C to +160°C Voltage on VDD with respect to VSS ......................................................................................................... -0.3V to +4.0V Voltage on any pin that is not 5V tolerant with respect to VSS(5) ....................................................-0.3V to (VDD + 0.3V) Voltage on any 5V tolerant pin with respect to VSS when VDD < 3.0V(5) ....................................... -0.3V to (VDD + 0.3V) Voltage on any 5V tolerant pin with respect to VSS when VDD  3.0V(5) .................................................... -0.3V to 5.6V Voltage on VCAP with respect to VSS ...................................................................................................... 2.25V to 2.75V Maximum current out of VSS pin.............................................................................................................................60 mA Maximum current into VDD pin(2).............................................................................................................................60 mA Maximum junction temperature.............................................................................................................................+155°C Maximum current sourced/sunk by any 2x I/O pin(3)................................................................................................2 mA Maximum current sourced/sunk by any 4x I/O pin(3)................................................................................................4 mA Maximum current sourced/sunk by any 8x I/O pin(3)................................................................................................8 mA Maximum current sunk by all ports combined ........................................................................................................10 mA Maximum current sourced by all ports combined(2)................................................................................................10 mA Note1: Stresses above those listed under “Absolute Maximum Ratings” can cause permanent damage to the device. This is a stress rating only, and functional operation of the device at those or any other conditions above those indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions for extended periods can affect device reliability. 2: Maximum allowable current is a function of device maximum power dissipation (see Table27-2). 3: Unlike devices at 125°C and below, the specifications in this section also apply to the CLKOUT, VREF+, VREF-, SCLx, SDAx, PGECx, and PGEDx pins. 4: AEC-Q100 reliability testing for devices intended to operate at 150°C is 1,000 hours. Any design in which the total operating time from 125°C to 150°C will be greater than 1,000 hours is not warranted without prior written approval from Microchip Technology Inc. 5: Refer to the “Pin Diagrams” section for 5V tolerant pins.  2009-2012 Microchip Technology Inc.

dsPIC33FJXXXMCX06A/X08A/X10A APPENDIX A: MIGRATING FROM dsPIC33FJXXXMCX06/ X08/X10 DEVICES TO dsPIC33FJXXXMCX06A/ X08A/X10A DEVICES The dsPIC33FJXXXMCX06A/X08A/X10A devices were designed to enhance the dsPIC33FJXXXMCX06/ X08/X10 families of devices. In general, the dsPIC33FJXXXMCX06A/X08A/X10A devices are backward-compatible with dsPIC33FJXXXMCX06/X08/X10 devices; however, manufacturing differences may cause dsPIC33FJXXXMCX06A/X08A/X10A devices to behave differently from dsPIC33FJXXXMCX06/X08/X10 devices. Therefore, complete system test and characterization is recommended if dsPIC33FJXXXMCX06A/X08A/X10A devices are used to replace dsPIC33FJXXXMCX06/X08/X10 devices. The following enhancements were introduced: • Extended temperature support of up to +125ºC • Enhanced Flash module with higher endurance and retention • New PLL Lock Enable Configuration bit • Added Timer5 trigger for ADC1 and Timer3 trigger for ADC2  2009-2012 Microchip Technology Inc.

Note the following details of the code protection feature on Microchip devices: • Microchip products meet the specification contained in their particular Microchip Data Sheet. • Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. • There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. • Microchip is willing to work with the customer who is concerned about the integrity of their code. • Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.” Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products.
